Second Pipe test

We have an Onyx Infinite Reality with 4 RM6s per pipe, dual pipe system with
16 R10000 CPUs. Is it possible to set up the second pipe so that missed
frame rates do not interfere with the first pipe? Where does Isect timing
go and how could it interfere with frame rates. I have an idea for an odd
use of Intersection geometry, but I want to make sure that I could set up a
test on the second pipe without interfering with the first pipe's real time
performance.... The first pipe MUST maintain 20hz real-time performance for
our application. It could even be a separate program as long as it in no
way interferes with the primary display's processes (APP_CULLDRAW_ISEC +
five extra processes). By my figuring we are using only half of our
processors and have a little room for growth <grin>.... I've utilized the
second pipe only as an expanded display (i.e. four quadrant display of the
same scene to be rendered at an effective resolution of 3200x2400), and have
never tried to run something completely different than the primary display
on the second pipe and I don't want to step on Performer's toes.... We have
Performer 2.1 and are Beta testing Performer 2.2 if either will help....
Performer 2.1 is preferred because we do not use the Beta Test on our
primary Real Time display....
